RG-4 does not understand humanoid suggestions. Thread - Megabyte Punch

Chain-hook weapon: A special ability from the chest that does no damage on its own but allows you to hook on to an enemy for a few moments so as you punch them back they come flying towards you again for additional punch-time joy.

Laser-beam weapon: A special ability that fires thin long streams of lasers, it does not have to do any more damage then other projectile weapons, eye-beam lasers seem appropriate.

Glide-type wings: A passive which allows you to fall slower but takes up a shoulder slot normally reserved for flight.

Damage reflection modules: A passive which does not reduce incoming damage, only returns a small portion of damage to enemies per hit taken.

Non-Item suggestion: The ability to look up and down while blocking to see what is just off screen

Cool!
